TIRE-ARMOR.

Specification of Letters Patent. 1 P t t M 2, 1915 Application filed Septemher 16, 1913. Serial No. 790,053.

T 0 all whom/it may concern Be it known that I, JAMES H. ANDERSON,

a citizen of the United States, residing at One object of the invention is toprovide a combined tread armor and antis'kidding device. I 1

Another object is to provide a protective casing for the tire on which is mounted an antiskidding tread.

Other objects and advantages will be apparent from the following description, when taken in connection with the accompanying drawings.

In the drawings: Figure 1 isa side elevation of a portion of a tire made in accordance with my invention. Fig. 2 is a transverse section through the tire. Fig. 3 is a perspective view of a portion of the movable tread. Fig. 4 is a perspective view of a portion of the tire casing.

Referring particularly to the accompanying drawings, 10 represents an ordinary single tube pneumatic tire which is adapted to be incased Within my improved protector.

My casing comprises the oppositely disosed concavo convex ringsl] which emrace the tire on the sides thereof. Each of the rings is provided with annular flanges extending inwardly toward the center of the wheel as indicated at 12, these flanges being arranged to receive the clamping bolts 13 which pass through the rim 14: and securely clamp the sections of the casingon the tire and to the rim. The rim has the circumferential extending channels 15 on opposite sides thereof to receive the braces 16 carried 1 On the outer'peripheries of the rings 11,namely the portions disposed at the tread of the tire are provided with .circular series of outwardly radiating projections 17 and recesses 18. .The said peripheries of the rings 11' are spaced apart to receive therebetween the inwardly projecting circumferential rib 19 formed on the armor tread 20. This armor 20 is in the form of an endless metal band, and has on its opposite sides the shoulders 21, these shoulders projecting below the perlpheral portions 17. The peripheral faces 17 of each of the rings 11 are slightly inclined toward the center of the tread, as

well as the projections thereof. The shoulders 21 are inclined in a manner corresponding to the peripheries of the rings and are also formed with a plurality of-recesses 22 and projections 23 for interlocking engagement with the projections and recesses of the rings 11. The rib 19 has its inner face concaved as indicated at 24 and bears against the outer or tread portion of the tire 10 between the peripheries of the rings 11. The outer or tread face of the ring 20 is provided with the corrugations 25 to prevent skidding of the tire.

The projections and recesses of the rings 11 and the shoulders 21 have a slight play of approximately one-fourth of an inch or more, and are always in engagement. Thus the tread member 20 can move bodily vertically, but is prevented from'lateralmovement between the peripheries of the rings 11 and alsofrom circumferential or creeping movement thereon by means of the projections and recesses.

lVith an armor and a casing of this character, a much cheaper grade of tire can be used, and the same be thoroughly protected both on the sides and at the tread.

\Vhat is claimed is In a tire protector, a casing comprising two concavo-convex rings arranged on opposite sides of a pneumatic tire, both the inner and outer portions of the rings being extion engaging the pneumatic tire and later- In testimony whereof, ll afiix my signature,
